The automotive industry has emerged as one of the most significant end-use sectors for polyoxymethylene (POM), where the material is increasingly adopted to replace metal components owing to its favorable strength-to-weight ratio. As manufacturers seek to reduce overall vehicle weight without compromising performance, POM has become an ideal material for key automotive components.

The Lightweighting Imperative

The demand for lightweight materials that enhance fuel efficiency in vehicles appears to be a significant driver for POM adoption. Every kilogram of weight reduction contributes to improved fuel economy and reduced emissions, making material selection critical in modern vehicle design. POM offers the perfect balance of strength and weight, enabling substantial weight savings compared to metal alternatives.

Key Automotive Applications

POM finds extensive application across various automotive systems:

Fuel Systems

  • Fuel pump modules and components

  • Fuel line clips and connectors

  • Fuel system components requiring chemical resistance

Interior Mechanisms

  • Door-lock mechanisms

  • Seat adjustment assemblies and systems

  • Power sliding console components

  • Interior trim and structural components

Under-the-Bonnet Components

  • Gears and drive components

  • Bearings and bushings

  • Support brackets and structural housings

  • Pump components

Electrical and Electronic Systems

  • Relays and electrical connectors

  • Coil insulation and HVAC components

  • Pulleys and connectors

Sustainability Innovations in Automotive POM

A significant milestone in automotive POM applications is the adoption of polyacetal resin made from captured CO2 for fuel pump modules. POM ECO-C solutions offer drop-in choices that provide more sustainable components while ensuring performance and helping automakers meet sustainability goals.

The use of recycled materials in POM components is also gaining traction. The Power Sliding Console winner at the 2025 SPE Automotive Innovation Gala utilized Celcon® POM for structural components, supporting sustainability goals through easier recycling and increased sustainability.

Performance Requirements

Automotive POM components must meet stringent performance requirements:

  • Excellent wear resistance for moving parts

  • Chemical resistance to fuels, oils, and automotive fluids

  • Dimensional stability across temperature ranges

  • Low friction for smooth operation

  • High strength for structural integrity

Enhanced Formulations for Automotive Applications

Specialized POM grades have been developed for demanding automotive applications. Compounds with glass fiber and PTFE reinforcement offer improved sliding/wear and heat-stabilized properties, making them suitable for gear wheels, roller bearings, and functional components.

The Electric Vehicle Opportunity

The growing penetration of electric vehicles is reinforcing demand for POM globally. EVs require precision components for battery systems, electric motors, and power electronics where POM's combination of electrical insulation, dimensional stability, and lightweight characteristics provides significant advantages.

Future Trends

As automakers continue to pursue sustainability goals and weight reduction targets, the role of POM in vehicle design is expected to expand. Innovations in manufacturing processes and the development of new POM grades tailored to specific automotive applications will drive continued growth in this segment.
